But this is not enough; it is not enough that to men who are already seeking the good the good should appear in all its full attractiveness.

It must be capable of being made attractive for those who do not know it, and who have never sought it, but who have, on the contrary, always turned away from everything that is supposed to lead to it.

It must be able, in other words, not only to satisfy the virtuous of the wisdom of their virtue, it must be able to convince the vicious of the folly of their vice.

Vice is only bad in the eye of the positive moralist because of the precious _something_ that we are at the present moment losing by it.

He can only convince us of our error by giving us some picture of our loss.
